Question
Solve the equation
Solve for x
Solve for r
Solve for y
x=∣y∣rx=−∣y∣r
Evaluate
x2y2=r2
Rewrite the expression
y2x2=r2
Divide both sides
y2y2x2=y2r2
Divide the numbers
x2=y2r2
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±y2r2
Simplify the expression
